    The 4 D’s of West Nile Virus Prevention


    The best way to protect yourself, your family and your community from mosquito bites, and West Nile Virus is to follow the four D’s: Drain, Dusk/Dawn, Dress, DEET.

    DRAIN: Drain or empty standing water around your home and neighborhood, since that is where mosquitoes lay their eggs.

    DUSK/DAWN: Take extra care to use repellent and protective clothing during evening and early morning (dusk and dawn) or consider avoiding outdoor activities during these times when mosquitoes are most active.

    DRESS: Dress in long sleeves and pants during dusk and dawn or in areas where mosquitoes are active. Wearing light-colored clothing may also help prevent being bitten.

    DEET, Picariden or Oil of Lemon Eucalyptus: Wear insect repellant containing either DEET, Picariden or oil of lemon eucalyptus.
    • Follow label instructions
    • Apply repellants to exposed skin and/or clothing.
    • Never use repellants over cuts, wounds or irritated skin
    • If using DEET, choose the concentration that best fits the amount of time spent outside. 25 percent DEET lasts up to 5 hours, 5 percent lasts 45-90 minutes. Use a concentration of 30 percent or less for children.
    • DEET should not be used on children less than 6 months of age. Oil of lemon eucalyptus should not be used on children less than 3 years of age.
